A Huntsville legislator says he's working on changes to his bill allowing an extract from marijuana to be used to treat children's seizures from epilepsy.

Republican Sen. Paul Sanford says he will join other advocates to announce the changes Tuesday and he hopes it will improve the bill's chance of passing.

Sanford's bill was on the Senate's work agenda Thursday, but the Senate broke for the weekend without getting to it. Senate President Pro Tem Del Marsh says he expects it to be back on the work agenda on Tuesday.

A bill planned for the upcoming session of the Alabama Legislature would legalize a substance derived from marijuana that is believed to help control seizures in children.

Republican Rep. Mike Ball of Madison told al.com that he plans to sponsor the bill to allow parents of children with certain neurological and epileptic disorders to possess cannabidiol. He says it doesn't produce a high and has no street value.
